Did you keep your original pipes?

cheers Dog but I don't think it applies to standard motor vehicles as they are not classified as LVV

the bike shops sell a lot of Yoshi equiped new bikes so I will rely on their WOF service to pass the new test subjective as it is

LVV applies to any vehicle and part thereof which is not a standard production or original factory equipment unit. Insurance cos have asked for years as to whether a vehicle is modified. Could be the exhaust, mags, Recaro seats, steering wheel...whatever. In theory, LVV covers the same sort of stuff.

Having a modified vehicle doesn't automatically mean your insurance is invalid. In fact, your insurance should still pay out even if your car doesn't have a wof, if you can prove it was in a warrantable state at the time of the accident. However, they will almost certainly try it on and reject a claim with that as an excuse.

I'm imagining that WoFs issued by a motorcycle shop are going to be more lenient on the subjective noise test, up to a level. They'll want the business but not the flak from the MOT or LTSA for issuing duff WoFs. So if your bike's exhaust is bordering on dodgy, a shop should be a better bet than VTNZ's gang of old duffers.

I never said that. But they do ask, and if you get your $3000 mags stolen the insurer will rightly reject the claim on the basis that they believed your car had standard rims.
The issue though is LVV - which covers areas such as compliance with regulations, fit for purpose handling etc, and these are things in which insurers are also interested.

My WoF is due in the new year before the law change. Hopefully the novelty of the new laws will have worn off by the time it becomes due again.

It would be asking for trouble to turn up at a testing station in June with a noisy exhaust. If your warrant is due in June, renewing it in May might be a good move.

Meantime, maybe I ought to print out the Db figures from the Arrow website...
Just to eliminate, as far as possible, the need for anyone to actually exercise their subjectivity.

[jrandom]

if your original can contained a cat...

[SPman]

Most aftermarket cans should be OK - my Yoshi had a 95db sticker on it and that sounded about right.

The loudest I've heard of was a guy in the UK who turned a CBR250 into a replica old Honda racer, complete with 4 megaphones and was asked to leave the track on his first visit - he tested at 143 db!

[Ixion]

105 ??? Now that is serious noise. My Yoshi is about 87dB, which is fine, and has been on the bike 'since it was new' - but how to prove that? Seems the LVVT guy here will just give bikers a tick cos he believes the law is an ass...

A gotcha to be aware of . Most dB numbers stamped on pipes will be as a result of a "drive by" noise test. Which gives different results to our (new) "shove the microphone up the exhaust " method.

Roughly speaking, 86dB by drive-by is reckoned about 100 dB by mike-up-pipe.

Not so with mine. That 87dB was measured with the mic about 4 feet behind the stationary bike in my garge, bike revving at about 5000.
And there are no ratings stamped into my Yoshi or affixed etc (that I can see)

[James Deuce]

My Yoshi is about 2 decibels. I can hear the battery box rusting over the exhaust noise.
